Wireless communication networks typically include wireless communication devices which, via wireless access nodes, communicate over wireless links with further communication networks and equipment. In many examples of wireless communication systems, the wireless communication devices can receive overhead communications from the wireless access nodes in addition to exchanging user communications.
Many overhead communication portions are shared by all wireless communication devices in communication with a particular wireless access node. One example use of the shared overhead communications is power control, which can be used to control a transmit power level of the wireless communication devices. In examples of shared power control, a transmit power level for user communications is increased or decreased for all wireless communication devices simultaneously.
